it is just a regex.
first of all i m modifying the solution.
pl refer to this

Quote:
echo "myfile.ext.ext" | sed 's/.*\.\([^.]*$\).*/\1/p'
it is searching for the pattern like this..

.* - anything
\. - literal dot.
[^.]*$ - anything after dot except dot at the end.
\(..\) - save the regex found
\1 - replace the regexp saved.

in previous solution i was first searching for the pattern.

NAME
xkbcomp - compile XKB keyboard description SYNOPSIS
xkbcomp [-option...] keymap-source OPTIONS
Produce a C header file as output (.h extension). Specifies top-level directories to be searched for files included by the keymap descrip- tion. Specifies a map to be compiled from an XKB directory file (not implemented yet). Specifies a name for the generated output file. The default is the name of the source file with an appropriate extension for the output format. Controls the reporting of warnings during compilation. A warning level of 0 disables all warnings; a warning level of 10 enables them all. Generate a source description of the keyboard as output (.xkb extension). Generate a compiled keymap file as output (.xkm extension). DESCRIPTION
The xkbcomp keymap compiler converts a description of an XKB keymap into one of several output formats. The most common use for xkbcomp is to create a compiled keymap file (.xkm extension) which can be read directly by XKB-capable X servers or utilities. The keymap compiler can also produce C header files or XKB source files. The C header files produced by xkbcomp can be included by X servers or utilities that need a built-in default keymap. The XKB source files produced by xkbcomp are fully resolved and can be used to verify that the files which typically make up an XKB keymap are merged correctly or to create a single file which contains a complete description of the keymap.
